DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a decorative glass panel, a method of manufacturing the same, and a dot screen used herein will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

2 is a flowchart illustrating a method of manufacturing a decorative glass panel of FIG. 1. FIG. 3 is a cross-sectional view of a decorative glass panel of FIG. 1, Fig. 8 is a view for explaining the corrosion step included in the manufacturing method of the glass panel.

1 to 3, a method for manufacturing a decorative glass panel according to an embodiment of the present invention includes a decorative glass panel in which a three-dimensional effect is produced on the glass by an optical illusion between a dot pattern formed on both sides of the glass and a dot pattern, And includes a preparation step S1, a corrosive ink printing step S2, a corrosion step S3, a corrosive layer removing step S4 and a halftone dot pattern layer forming step S5.

The preparation step S1 is a step of bringing the dot screen 20, in which the circular mask 10 is joined at each lattice intersection, into close contact with the surface of the cleaned glass layer 100, as shown in Fig. It is preferable that the mask 10 is cylindrical and its thickness is thicker than the thickness of the grid frame.

The corrosive ink printing step S2 is a process of screen printing the corrosive ink 30 on the surface of the glass layer 100 in the removed area A1 exposed between the masks 10. The corrosive ink 30 flows into the surface of the glass layer 100 through a space between the grating pits-> the mask 10 to corrode the glass layer 100.

The erosion step S3 is a step of forming the dot pattern layer 200 in an embossed form while the remaining area A2 not corroded is less etched as the removed area A1 of the glass layer 100 is deeply penetrated in the thickness direction to be.

The corrosive layer removing step S4 is a step of washing and removing the removed area A1 of the glass layer 100 which has been corroded. Only the dot pattern layer 200 is left while the removal region A1 of the glass layer 100 is removed.

1, the halftone dot pattern layer forming step (S5) is performed by screen printing the halftone dot pattern 310 (see FIG. 4) on the back surface of the glass layer 100 by using the first thermosetting ink, drying and curing Thereby forming a halftone dot pattern layer 300.

Also, in this step, a pattern 320 of the user's specific pattern (see FIG. 4) is also printed together with the dot pattern layer so that the desired pattern pattern of the user is three-dimensionally displayed on the dot pattern layer acting as a three- Effect can be produced.

The protective layer forming step (S6) may further be included to protect the halftone pattern layer (300). The protective layer forming step S6 is a step of forming a protective layer 400 on the surface of the halftone pattern layer 300 using a second thermosetting ink by screen printing the vacuum pattern 410 (see FIG. 4) . The undulation pattern 410 is a pattern that smoothly fills the upper surface of the halftone dot pattern layer 300.

In the protective layer forming step (S6), it is preferable to use a mesh screen having a small bow, a screen plate having a large string angle, a low-resolution output device, and a high-density ink than the halftone dot pattern layer forming step (S5).

This is because the protective layer 400 does not have to have a higher printing precision (resolution) than the halftone dot pattern layer 300, the resistance of the screen plate is small, and the upper surface of the halftone dot pattern layer 300 can be filled with a high concentration .

On the other hand, the halftone dot pattern layer 300 is required to have a precise pattern shape, a relatively large resistance of the screen plate, and a relatively low ink concentration (viscosity) in terms of print quality.

The first thermosetting ink used in the halftone pattern layer forming step (S5) is an epoxy-based resin showing a first viscosity, and the second thermosetting ink used in the protective layer forming step (S6) is an epoxy- It is more preferable to use a two-component type resin which is mixed and exhibits a second viscosity lower than the first viscosity.

This is because it is advantageous that the viscosity of the ink is high since the halftone pattern layer 300 requires high print quality and shape accuracy and the protective layer 400 is required to have a smooth and uniform ink application on the entire surface of the halftone pattern layer 300 This is because the spreadability of the ink is good and the two-pack type resin is superior in durability and strength to the one-pack type resin.

Hereinafter, specific embodiments of the present invention will be described. FIG. 4 is a photograph showing an actual process image to which the method for manufacturing a decorative glass panel of FIG. 1 is applied.

Preparation step (S1):

As shown in FIG. 4 (a), a glass layer 100 is prepared with a hard or semi-transparent hard material such as reinforced / unreinforced glass such as glass, white glass, bronze glass or acrylic or the like with a thickness of about 3T to 10T . If the thickness of the glass layer 100 is thinner than 3T, the three-dimensional feeling and perspective of the glass may be deteriorated. If the thickness is thicker than 10T, the sharpness of the glass may be deteriorated.

The contaminants and stains on both sides of the prepared glass layer 100 are cleaned using a washing machine. The cleaning solution dilutes 5% of the surfactant and 2% of the polymer in 100% of water and uses a washing machine to remove contaminants and stains to optimize the glass surface.

Next, the dot screen 20 composed of the mask 10 having a diameter of 0.5 to 2 pi and a pitch of 0.1 to 0.2 mm was brought into close contact with the surface of the glass layer 100.

Corrosive ink printing step (S2):

A corrosive ink (aqueous ink) was applied onto the dot screen 20 and infiltrated into the surface of the glass layer 100.

Corrosion step (S3):

After printing of the corrosive ink, time must be observed. The time is preferably 20 seconds for 100th, 30 seconds for 150th, and 40 seconds for 200th.

Corrosion layer removal step (S4):

As shown in Fig. 4 (b), a dot pattern layer 200 is formed on the surface of the cleaned glass layer 100 in the form of an embossed pattern.

Step of forming a halftone dot pattern layer (S5)

In the halftone pattern layer forming step (S5), pearl, holographic, mirror, solid, dye, pigment and the like may additionally be mixed or mixed in order to amplify the sharpness of color and gloss of glass and to increase 3D and stereoscopic effect .

Protective layer forming step (S6):

4 (d), the backing pattern 410 was printed on the surface of the halftone dot pattern layer 300 and dried by a heat curing lamp to form the protective layer 400. The protective layer 400 has a higher durability and strength than the halftone dot pattern layer 300 and protects the protective layer 400.

Screen printing of the protective layer 400 was carried out using a screen mesh of 100 to 150 threads and a screen plate having a string angle of 90 degrees. Also, an output device having a resolution of 0 PPI, a second thermosetting ink of a concentration of 100 PPM was used.

The second thermosetting ink was prepared by mixing two-component thermosetting organic CST-2120A ink and organic CST2120B at a predetermined ratio. The composition ratio of the CST-2120A ink is as described above, and the composition ratio of the CST2120B ink is 30 to 80 parts by weight of a modified polyamine, 5 to 40 parts by weight of an additive, 5 to 40 parts by weight of an ETC It is a colorless, transparent liquid with a viscosity of 100 CPS to 120 CPS.
